Managed to get this set in the silent auction for $20
The bad news: 19AP4 is toast
The good news: Cabinet has had a decent amateur refinish job and the knobs were sitting inside a coffee cup tucked between the picture tube and chassis.....but that's not all!
After giving the chassis a once over, I'm convinced this was a working set that had a picture tube failure. The recap job here is artistry. Whoever did this job used some funky 2 x 50 uF 500V UK manufactured caps and mounted them neatly in the chassis. Not really any info out there on them, they say FAC/RD37DUK 95-42.
They make everything look so neat, in the midst of what would be long terminal strips of caps mounted on the chassis if I were the one doing the job. Even the disc caps are all new.
Also, there's a funky relay underneath, with one wire labeled COIL. A quick glance shows that the wires go between the power transformer and the twin 5U4s. Could be some type of surge surpression that someone built in, like a soft start circuit?
Anyway, I'd love to shake the hand of the man who did this work.....
